Portland General Electric Announces First Quarter 2023 Results
•Entered an agreement to construct a 200 MW company-owned battery storage project, a $360 million investment; also entered a storage capacity agreement to secure an incremental 200 MW of battery storage
•Financial results reflect strong energy demand, continued energy-market volatility, and effective cost controls
•Reaffirming 2023 adjusted earnings guidance of $2.60 to $2.75 per diluted share
PORTLAND, Ore. -- Portland General Electric Company (NYSE: POR) today reported net income based on generally accepted accounting principles (GAAP) of $74 million, or $0.80 per diluted share, for the first quarter of 2023. This compares with GAAP net income of $60 million, or $0.67 per diluted share, for the first quarter of 2022, which included the $0.14 per diluted share deferral reversal charge related to the 2022 General Rate Case Final order. After adjusting for the impact of the deferral reversal charge, first quarter 2022 non-GAAP net income was $72 million, or $0.81 per diluted share.
“This quarter we advanced Oregon’s clean energy transition, strengthened our organization, and tackled challenging energy markets,” said Maria Pope, PGE President and CEO. “We are excited to announce new battery storage projects that will be critical to serving customers and the integration of renewable resources.”
First Quarter 2023 Compared to First Quarter 2022
Total revenues increased, driven by higher demand from digital and semiconductor customers, colder weather, and a favorable customer price mix. Purchased power and fuel expense increased primarily due to increased loads combined with higher power market prices. Operating and administrative expenses remained largely flat, excluding amortization of major deferrals, due to continued implementation of operational efficiencies and cost controls. Other income increased due to gains on non-qualified benefit plan assets from improved market performance.
Company Updates
2021 All-Source Request for Proposal Update
After a robust and competitive bidding and negotiating process, PGE has entered an agreement to construct a 200 MW PGE-owned lithium-ion battery energy storage system (BESS) and entered a storage capacity agreement for a 200 MW BESS. All BESS projects will be emission-free dispatchable capacity resources directly interconnected to PGE’s system. Project agreements include:
1

PGE-owned Resource
•Seaside Grid - PGE and Eolian, L.P. entered into an agreement to construct a 200 MW BESS in Portland, Oregon. PGE will own the resource, with an investment of approximately $360 million, excluding AFUDC. The project has an estimated commercial operation date of June 30, 2025.
Capacity Agreement Resource
•Troutdale Grid - PGE and Eolian L.P. entered into a storage capacity agreement for a 200 MW BESS in Troutdale, Oregon. The project was subsequently acquired by NextEra Energy Resources, LLC, who will own the resource and will sell the capacity to PGE under a 20-year storage capacity agreement. The project has an estimated commercial operation date of December 31, 2024.
PGE continues to negotiate with a remaining 2021 All-Source RFP short-list bidder that could result in an agreement to construct a company-owned 75 MW BESS project. If parties are able to reach a definitive agreement, the Clearwater agreements and all BESS agreements would represent the final projects to be procured from the 2021 All-Source RFP. Resources required to meet remaining needs are anticipated to be procured through future acquisition processes, including but not limited to the 2023 All-Source RFP and future RFPs.
Resource Planning and 2023 All-Source RFP Updates
On March 31, 2023, PGE filed its first combined Clean Energy Plan (CEP) and Integrated Resource Plan (IRP) with the OPUC. PGE’s inaugural CEP articulates the Company’s strategy to meet the 2030, 2035, and 2040 emission reduction targets, as mandated by Oregon law, through an equitable transition to a decarbonized grid. The CEP is based on, and was filed in connection with, the Company’s 2023 IRP. The combined filing projects PGE’s resource and capacity needs over the next 20 years and proposes an Action Plan to meet near-term needs, subject to new state emissions reduction requirements.
Consistent with the IRP Action Plan and CEP, PGE filed notice with the OPUC in January 2023 that an RFP in 2023 is needed to procure resources to meet forecasted capacity needs and to make continued progress toward decarbonization targets. Additional milestones in the 2023 All-Source RFP will take place throughout 2023 and 2024.
2024 General Rate Case Update
On February 15, 2023, PGE filed with the OPUC a General Rate Case based on a 2024 test year (2024 GRC). Regulatory review of the 2024 GRC (OPUC Docket UE 416) will continue throughout 2023, with a final order expected to be issued by the OPUC in December 2023, for new customer prices effective January 1, 2024.
At-the-market Offering Program
On April 28, 2023, PGE registered a $300 million at-the-market offering program. Any proceeds from the issuances of common stock will be used for general corporate purposes and investments in renewables and non-emitting dispatchable capacity.
Quarterly Dividend
As previously announced, on April 21, 2023, the board of directors of Portland General Electric Company approved an increase in the annual dividend of 5.0%, or $0.09 per share, declaring a quarterly common stock dividend of $0.475 per share. The quarterly dividend is payable on or before July 17, 2023 to shareholders of record at the close of business on June 26, 2023.
2023 Earnings Guidance
PGE is reaffirming its estimate for full-year 2023 adjusted earnings guidance of $2.60 to $2.75 per diluted share based on the following assumptions:
2

•An increase in energy deliveries between 2.5% and 3%, weather adjusted;
•Normal temperatures in its utility service territory;
•Hydro conditions for the year that reflect current estimates;
•Wind generation based on five years of historical levels or forecast studies when historical data is not available;
•Normal thermal plant operations;
•Operating and maintenance expense between $695 million and $715 million which includes approximately $45 million of storm, wildfire and related deferral and other expenses that are offset in revenue and other income statement lines;
•Depreciation and amortization expense between $445 million and $465 million;
•Effective tax rate of 15% to 20%;
•Cash from operations of $550 to $600 million;
•Capital expenditures of $1,325 million; and
•Average construction work in progress balance of $560 million.

Non-GAAP Financial Measures
This press release contains certain non-GAAP measures, such as adjusted earnings, adjusted EPS an d adjusted earnings guidance. These non-GAAP financial measures exclude significant items that are generally not related to our ongoing business activities, are infrequent in nature, or both. PGE believes that excluding the effects of these items provides a meaningful representation of the Company’s comparative earnings per share and enables investors to evaluate the Company’s ongoing operating financial performance. Management utilizes non-GAAP measures to assess the Company’s current and forecasted performance, and for communications with shareholders, analysts and investors. Non-GAAP financial measures are supplementary information that should be considered in addition to, but not as a substitute for, the information prepared in accordance with GAAP.
Items in the periods presented, which PGE believes impact the comparability of comparative earnings and do not represent ongoing operating financial performance, include the following:
•Non-cash Wildfire and COVID deferral reversal charge associated with the year ended 2020, resulting from the OPUC’s 2022 GRC Final Order earnings test.
PGE's reconciliation of non-GAAP earnings for the quarter ended March 31, 2022 is below.
